“…3b and 3d). Although this finding aligns with some of the previously mentioned studies 25,26) , it was not in accordance with the findings of Moshonov et al In our opinion, this distinction emerged as a result of higher pulse repetition rate and lower pulse energy. For this reason, the laser groups with a higher pulse repetition rate caused deeper craters and grooves on the enamel surface (Figs.…”

“…The findings revealed that, there was no difference between the Er:YAG laser with acid etching and conventional techniques. Moreover, fissures prepared with the Er:YAG laser alone showed the highest degree of microleakage 26) . In the present study, the higher microleakage was found in both Er:YAG laser groups used alone according to all other groups.…”

“…In our opinion this difference may be caused by the higher pulse repetition rate. Additionally, we prefered the primary teeth unlike above-mentioned studies 26,27) . In pediatric dentistry, we think that PFSs applications in which lasers used alone for the surface conditioning procedure show lower microleakage and unfilled area according to laser combined acid etching.…”

The purpose of this study was to evaluate the effects of different surface conditioning procedures on microleakage and unfilled area proportions of three fissure sealants(Aegis, Helioseal and Helioseal F) in primary molar teeth. One hundred and fifty teeth were randomly divided into five main groups according to surface conditioning procedures. Main groups were; acid-etching(Group A); laser 3.75 W(Group B) and 5 W(Group D); acid-etching combined with laser 3.75 W(Group C) and 5 W(Group E). Samples were aged by thermocycling and water bath. Afterwards, they were immersed in basic fuchsin solution for 24 h and bucco-lingual sections were obtained from each tooth. Digital images were taken using a stereo-microscope and the microleakage and unfilled area proportions were assessed by using a software system. Consequently, Aegis FS containing amorphous calcium phosphate was found to exhibit the lowest microleakage in all surface conditioning procedures. Unfilled areas were not detected in Groups C and E of all FSs.

“…Recently developed giomer-based fissure sealant material represents advantages of resinbased and glass-ionomer-based sealants. The use of flowable composites as fissure-sealant material was also Microleakage and penetration depth of different fissure sealant materials after cyclic thermo-mechanic and brushing simulation Hüseyin HATIRLI 1 , Bilal YASA 1 and Elif YASA suggested 9) . The preventive effect of pit and fissure sealing is mainly based on the ability of sealant materials to flow through pits and fissures and completely fill them without any gaps or air entrapments.…”

The aim of the study was to evaluate microleakage and the penetration-depths of different fissure-sealant materials applied with/ without enameloplasty after cyclic aging. One-hundred-sixty mandibular molars were divided into non-invasive and enameloplasty preparation groups and eight material subgroups, including: flowable composites (microhyrid, nanohybrid, and nanofilled), three resin-based (unfilled, filled, and highly-filled), a giomer-based, and a glass-ionomer-based fissure sealant. Specimens were subjected to two-year cyclic chewing and brushing simulation. After 5% basic-fuchsin dye penetration, specimens were sectioned and scored under stereomicroscope. Kruskal-Wallis statistical data showed that preparation type significantly affected the penetration of all tested materials (p<0.05), but not significantly affected microleakage (p>0.05). Flowable composites showed the best and the glass-ionomer-based sealant showed the worst penetration and microleakage. Slight preparation of fissures is not important in microleakage. However, enameloplasty significantly enhanced the depth of penetration of the sealants. Flowable composites offer promising results at the fissure sealing.

“…4) Therefore, alternative methods have been proposed for preparing fissures other than acid etching for sealant retention like air abrasion and laser. [5][6][7] In recent years, lasers has been suggested as a pretreatment method to roughen enamel. [6][7][8] The main advantages that have been ascribed to laser technology are the lack of vibration and pain during the prepara-…”

A comparative evaluation of retention of pit and fissure sealants placed with conventional acid etching and Er,Cr:YSGG laser etching: A randomised controlled trial

Aim:The aim of this study was to compare the retention rates of sealant placed either with conventional acid etching or Er,Cr:YSGG laser pretreatment of enamel surface. Materials and methods: This is a prospective, single blind randomised controlled clinical trial enrolling 200 permanent first molars in 50 patients, aged 6-12 years for sealant placement. Study followed split mouth design where each side of the arch was randomly allocated to the two treatment group. Group A(Acid etch group): 37 % phosphoric acid (Scotchbond, 3M ESPE, Seefeld, Germany) was applied for 15 seconds, rinsed with water for 20 seconds and then air-dried using air spray. Group L(Laser etch group): Fissures were prepared with an Er,Cr:YSGG laser system (Waterlase, BIOLASE Technology, San Clemente, CA, USA) emitting photons at a wavelength of 2.78 µm. Laser irradiation at 1.5 W (60% air and 40% water), in a noncontact mode, with a repetition rate of 20 Hz for 10seconds was used. Pit and fissure sealant (3M ESPE, Clinpro) was applied and cured for 20 seconds. One blinded, calibrated examiner, who was unaware of which preparation method has been used and who was not involved in the treatment procedures, evaluated the sealant at baseline and at 3, 6, 9 and 12 month follow-up visits. Results: It was observed that overall retention rate in group A was slightly higher as compared to group L at all time periods, however, the difference was statistically non-significant (p-value>0.05). Conclusion: Er,Cr:YSGG laser etching is comparable to acid etching in terms of retention and patient acceptability.

Effect of enamel preparation method on in vitro marginal microleakage of a flowable composite used as pit and fissure sealant

Abstract: It can be concluded that no significant difference was noted between the two types of enamel preparation when etching was performed. Preparing and treating the enamel surface exclusively by Er:YAG laser resulted in the highest degree of leakage.
